| Abstract |
OFDM-based radar enables high-precision target detection by leveraging wide bandwidth and multi-path reflection signal analysis. This study integrates the SUMO simulator with HFSS-based Ray Tracing to simulate vehicle mobility and radio wave propagation characteristics in a dynamic traffic environment. Back Projection and DBSCAN clustering algorithms are used to estimate the 3D positions and trajectories of detected targets. The results demonstrate the effectiveness of OFDM radar in real-world traffic scenarios by evaluating its detection performance and accurately reconstructing target movement paths. |
